2. Stainless steel - Wikipedia

   en.wikipedia.org/wiki/Stainless_steel

   Stainless steel, also known as inox, corrosion-resistant steel (CRES), and rustless steel, is an iron-based alloy containing a minimum level of chromium that is resistant to rusting and corrosion. Stainless steel's resistance to corrosion results from the 10.5%, or more, chromium content which forms a passive film that can protect the material ...

3. Brushed metal - Wikipedia

   en.wikipedia.org/wiki/Brushed_metal

   Brushed stainless steel or dull polished metal [1] is metal with a unidirectional satin finish. It is produced by polishing the metal with a 120–180 grit belt or wheel then softening with an 80–120 grit greaseless compound or a medium non-woven abrasive belt or pad. Commonly brushed metals include stainless steel, aluminium and nickel.

5. Bronze - Wikipedia

   en.wikipedia.org/wiki/Bronze

   Bronze, or bronze-like alloys and mixtures, were used for coins over a longer period. Bronze was especially suitable for use in boat and ship fittings prior to the wide employment of stainless steel owing to its combination of toughness and resistance to salt water corrosion. Bronze is still commonly used in ship propellers and submerged bearings.

   en.wikipedia.org/wiki/Babbitt_(alloy)

   The crankshaft and connecting-rod big-end bearings in current automobile engines are made of a replaceable steel shell, keyed to the bearing caps. The inner surface of the steel shell is plated with a coating of bronze , which is in turn coated with a thin layer of Babbitt metal as the bearing surface.

9. Gunmetal - Wikipedia

   en.wikipedia.org/wiki/Gunmetal

   Gunmetal ingot is a related alloy in which the zinc is replaced by 2% lead; this makes the alloy easier to cast but it has less strength. [2]Modified gunmetal contains lead in addition to the zinc; it is typically composed of 86% copper, 9.5% tin, 2.5% lead, and 2% zinc.
